The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Why the universe is expanding faster and faster remains one of the biggest open questions in physics. Current theories cannot ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

New quantum experiments may settle the century-old Einstein vs Bohr debate, revealing key insights into quantum behaviour.

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

New tech allows moon events to be accurately synchronised from Earth, paving the way for more spacecraft and people to work ...

Researchers from the Purple Mountain Observatory in China released LTE440, short for Lunar Time Ephemeris, in a recently ...

Time does not pass at the same speed on Earth and the moon; with lower gravity, lunar clocks run faster by around 56 ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.
